JAMES W. MORRIS .AND LESTER I.. BAYLES, OF OAKLAND, CALIFORNIA.

SICK-BED.

To all 'whom t may concern e it known that we, JAMES lll. MORRIS and LESTER L. BAYLEs, citizens of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Sick-Beds, of which the following is a specification.

ur invention is an improved sick bed.

In this specification and the annexed drawings, we disclose our invention in the form which we consider the best, but we do not limit our invention to such form because it may be embodied in other forms, and itis to be understood that in and by the claims following the description herein we intend to cover our invention in whatever form it may be embodied.

Referring to the drawings;

Figure l is an end View of a bed embodying our invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a plan of the litter.

Fig. 4 is an end elevation of the elevating mechanism.

Fig. 5 is a side view of the litter.

Fig. 6 is a fragmentary view of one of the elevating levers and leg of the litter in engagement with lsaid lever.

In the drawings, 1 indicates a bedstead which may be an iron bedstead, including a bed spring 2 and a mattress 3. A litter 4 includes a horizontal rectangular frame 5, a swinging frame 6 pivoted at 7 to the side members of frame 5, and legs 8 depending from the corners of frame 5. A sheet of canvas 9 is stretched over the frame 5 and secured to the side and end members thereof and has an opening 10 therein. A sheet of canvas l0 is stretched over the frame 6 and secured to the side and end members thereof. The litter normally rests upon the bedstead with the frames 5 and 6, and the canvas 9 and 10 upon the mattress 3, and the legs 8 depending outside the ends of the mattress and spring 2 but within and adjacent the side connecting rails 11 of the bedstead, the legs engaging the spring and mattress and the side rails and preventing shifting of the litter on the bedstead. The frames 5 and 6 and the legs 8 are preferably made of tubing.

An elevating machanism 12 is provided for raising anl lowering the litter 4 with relation to the mattress 3, which mechanism includes a frame 13 resting upon the floor Specification of Letters Patent.

Patented Dec. 28, 1920. serial No. 304,624.

beneath the bedstead; a pair of jack levers 14 and 15 respectively under the legs at the head and foot of the litter; links 16 and 17 upon which said levers are respectively pivoted and which are respectively pivoted to transverse members said members being connected by longitudinal frame member 20; a windlass 21 journaled in a windlass frame 22 of frame 13` the windlass frame being connected by connecting member 23 to transverse member 18, pulleys 24 and 25 connected to the inner ends of levers 14 and 15 respectively; pulleys 26 and 27 connected to transverse frame members 18 and 19 respectively; ropes 28 connected at their ends to frame member 18 and windlass 21 and passing through pulleys 24 and 26; and ropes 29 connected at their ends to frame member 19 and windlass 21 and passing through pulleys 25 and 27. The outer ends of levers 14 and 15 have notches 30 therein and upstanding lugs 31, the lower edge of the legs 8 resting in said notches and said lugs extending into the lower ends of the legs, thus maintaining the levers in operative engagement with said legs. One of the journals of the windlass 21 is formed into a crank 32 for turning the windlass. A ratchet 33 is secured to one of the journals of the windlass which is engaged by a pawl whereby the windlass is allowed to be turned in one direction to wind the ropes 28 and 29 thereon, but is prevented from turning in the other direction and unwinding said ro es.

pon turning the windlass 21 and winding the ropes 28 and 29 thereon the levers 14 and 15 are swung on their pivots and the litter 4 and the patient therein are elevated above the mattress 3 in which position of the litter a bed pan may be introduced between the mattress and the litter under the opening 10 for use. When so elevated air may circulate between the mattress and the litter and under the patient in the litter. The litter may be lowered upon the mattress upon unwinding the ropes from the windlass. The litter with the patient thereon may be lifted oii" the levers 14 and 15 and oli' the bedstead and carried about. The frame 6 may be inclined upwardly and held in such position by pillows placed under it, to support the body of the patient in an upwardly inclined position.

aving described our invention, we claim: l. In a sick bed, a litter` adapted to rest 18 and 19 of frame 13,

upon the bed mattress, legs depending from said litter, an elevating mechanism including levers upon which `said legs rest, and means Yfor swinging said levers to raise and lower said litter.

2. In a sick bed, a litter adapted to rest upon the hed mattress, legs depending from said litter, an elevating mechanism including levers upon which said legs rest, a windlass, and ropes connected to said Windlass and said levers for raising and lowering said litter.

3. In a sick bed, a litter adapted to rest upon the bed mattress, hollow legs depending` from the litter over the ends of the mattress and bed spring, levers formed with notches at one end in which the lower edges of said legs rest, lugs on the notched ends of said levers projecting into the lower ends of said legs, and means for swinging said levers to raise and lower said litter.

In testimony whereof we affix our signatures.
